Safety and Installation Guide
for Scheuten Solar Fusion P6-60 U
Photovoltaic Modules
United States and Canada
It is important that the information provided in this manual
is observed. These instructions should be read carefully
and observed fully before installation, initial operation and
during maintenance of photovoltaic (PV) systems that use
Scheuten PV modules. Please save these instructions for
later use and pass them onto your customers.
Danger! Risk of death or serious injury,
if not observed! It is crucial that any
work performed on PV systems is
carried out exclusively by skilled professionals who have
the respective training.
Module connectors pass direct current (DC) and a
dangerous voltage can be present when the module is
under load or exposed to light. Direct current can arc
across gaps and may cause injury or death when
improperly (dis)connected
Underwriters Laboratories (UL) Listing Information
This manual is intended to be used for CSA-listed Scheuten
Solar Fusion PV modules that can be identified by the CSA
logo on the label on the back of these modules.
This product meets or exceeds the requirements set forth by UL1703 for
PV Modules. This UL Standard covers flat-plate PV modules and panels
intended for installation on buildings or those intended to be
freestanding. To satisfy the listing for this product the modules must be
mounted with a rack or standoff structure. The CSA listing does not
include integration into a building surface because additional
requirements may apply. This product is not intended for use where
artificially concentrated sunlight is applied to the module.
1. General Instructions
All installations must be performed in compliance with the National
Electrical Code (NEC) or the Canadian Electrical Code and any
applicable local codes.
There are no user serviceable parts within the module. Do not
attempt to repair any part of the module. Contact your module
supplier if maintenance is necessary.
If the front glass is broken, or the back sheet is torn, contact with
any module surface or module frame might cause electric shock.
Use insulated tools to reduce your risk of electric shock.
Do not stand on, drop, scratch, or allow objects to fall on modules.
Do not install or handle the modules when they are wet or during
periods of high wind.
The applicable regulations pertaining to work
safety, accident prevention and securing the
construction site must be observed. Persons
and objects have to be secured against falling.
Any third party need to be protected against injuries and
damages.
2. Module Mounting
When installing Scheuten photovoltaic modules, local building
regulations and the relevant generally accepted rules of technology
must be adhered to at all times. In addition, you should always consult
with the local jurisdiction having authority to ensure adherence to all
applicable building codes and regulations.
Due to continuous innovation and product development for PV module
mounting hardware, and the diversity of PV applications, this
installation guide is subject to change without notice. When installing
Scheuten modules the mounting system vendors’ installation
instructions and this guide must be strictly adhered to. In the event the
vendor’s instructions are more rigorous than this guide, the vendor’s
instructions shall apply.
After unpacking the modules, inspect them carefully for any damage.
Inspect in particular all plastic parts, which are critical, to assure proper
reinforced or dual insulation.
PV modules may not be lifted at the connection
cables or the junction box.
Do not step on the modules.
The operating temperature of the modules must be between -40ºC
(-40ºF) and +85ºC (185ºF). To rule out extreme temperatures and
damage as a result, PV modules may not be subject to artificially
concentrated sunlight. Modules need to be mounted in a way that
allows for adequate ventilation of the module back-side to prevent the
build-up of heat which can affect performance. Modules should be
installed with a minimum standoff height of 1-1/2 in.
Figure 1 – Mounting Specifications
The design load of the modules is 75 psf (3600 Pascal).
Distributed loads from wind, snow and tare weight will affect the
modules. These will be carried by the glass plate of the laminate and
the frame made of anodized aluminum profiles. For this purpose, the
solar modules must be mounted to a stable substructure using a
suitable mounting system. Figure 1 shows module specifications and
suggested orientation of the module with respect to support rails.
Modules may be attached to support rails by bolting, clamping or other
acceptable means at the location shown.

2.1 Bolting Mounting Method
The factory mounting holes found in the long frame segments can be
used (see Figure 1- Mounting Specifications) to secure the modules to
suitable support structure. The frame must be secured at a minimum of
four points when bolting. The modules are bolted from the backside as
shown in Figure 2. Scheuten recommends using four (4) M6 or ¼ in.
stainless steel bolt assemblies to secure each module. Each assembly
should consist of a bolt, washer, lock washer and nut. The ¼ in. (M6)
bolting assembly should be secured with a torque wrench to a
tightening torque of 9 ft-lbf (12 Nm).

2.2 Mounting Using Topside Module Clamps
Clamps can also be used to secure modules to a suitable support
structure. When using clamps, they can be attached at the position
where the frame holes are found. The dimensions of the clamp
surfaces should be sized adequately. A surface area of at least
500 mm² (0.775 in
2
) is recommended. Module clamps and associated
hardware assemblies must be compatible with other materials to avoid
corrosion due to the use of dissimilar metals.
Scheuten Solar recommends installing support rails at a distance 32 in.
on-center so that modules may be clamped to support rails at
approximately 16 in. from module edge. This clamping location
coincides with the approximate location of the module mounting holes
shown in Figure 1. Modules are to be secured to the support rails
using topside module clamps which do not shade the module. Clamps
should be secured to a tightening torque of 20 ft-lbf. (28 Nm) for a 5/16
in. stainless steel bolt. The support structure and clamps must have a
design load of at least 75 psf (3600 Pa).
The loads detailed in this guide apply to the mounting methods
specified above. In appendix 2 other regular mounting methods are
described with different load regimes. For permission to mount
Scheuten modules using specialized PV mounting systems other than
those outlined above or in appendix 2, please contact Scheuten Solar.
Failure to do so will void the warranty and panel certification.
2.3 Additional information
Scheuten PV modules may not be used as overhead glazing. In case
of rooftop systems, fire protection must be compatible with the class C
fire rating of the modules. Forces impacting the frame profile at the
points of contact must not result in any deformation of the frame.
Crowding between frame and glass should be avoided at all costs. If
installed on an incline, the modules should be secured from sliding at
the eaves. Drainage openings must not be covered up. No additional
holes should be drilled into the unit for mounting purposes, for potential
equalization or for any other purposes. Any changes of this kind will
void the warranty.
3.0 Electrical Installation
Danger! Risk of death or serious
injury from electric shock! Do not
connect or disconnect modules
under load.
Scheuten PV modules may be used in systems that are accessible
without restrictions if installed in accordance with instructions
(application class A, IEC 61730 or safety class II, IEC 61140).
Additionally, installation shall be in accordance with CSA C22.1, Safety
Standard for Electrical Installations, Canadian Electrical Code, Part 1.
Despite protection against accidental contact, under unfavorable
conditions if several modules are connected in series, hazardous
voltage of several hundred volts may be present during installation. For
this reason, work on the modules may only be performed by qualified
skilled professionals. The manufacturer’s instructions of the other
components being used, especially those of the inverter, are to be
observed.
Danger! Risk of death or serious
injury from electric arcs!
Exposed to light under load and especially in the event of a short
circuit, high levels of direct current can result in dangerous electric
arcs, if, for example, the connection between two PV modules is
separated.
The unit may only be connected to the main power supply by a
licensed skilled professional. Work to be performed is to be
coordinated with the electricity network provider. The photovoltaic
system must be approved by an electrician who is responsible to the
operator and the local electricity company for assuring installation was
carried out correctly.
3.1 Junction box
The junction box is of protection class IP 65. Observe the details listed
on the cover. The box cover may only be opened in exceptional cases
and exchange of parts in and on the junction box is only allowed by a
skilled electrician authorized by Scheuten Solar.
Within the junction box are the bypass diodes, Diotec type SB1240
1
.
3.2 Connection cables and plug-in connectors
The integrated connection cables are dual insulated and UV resistant.
The wire diameter of the connection cables is 6 mm² (0.0093 in
2
). For
wiring, the connection cables have pre-assembled plug-in connectors
with reverse polarity protection. Because of its safe design features,
accidental contact with current-carrying cables can be ruled out entirely
when used correctly. When connected, protection class IP 65 applies.
The connectors may only be plugged in when dry. Special attention
should be given to assure a seamless connection.
In general, the connection cable should not be subject to any tensile
loads. Wires should be attached to the mounting system using UV
resistant cable ties to avoid chafe marks from movements or tensile
loads.
3.3. Module Connection
Modules may be connected in series (voltage additive) and/or in
parallel (current additive) to produce the appropriate electrical output.
PV module interconnections should be 90ºC wet-rated conductors. An
allowable wire type is using USE-2 or PV single-wire conductor cable
for exposed applications. For field connections use insulated minimum
no.12 AWG copper wires rated for a minimum of 90ºC.

When connecting modules in parallel, each module (or series string of
modules so connected) shall be connected according to the maximum
series fuse as specified. Applicable regulations should be observed to
assure safety and maintain the warranty when working with electrical
devices. A maximum system voltage of 600 V must not be exceeded,
not even at especially low temperatures.
Depending on its set-up location and environmental conditions, a PV
module may supply higher voltages and / or higher current when
compared to standard testing conditions. For this reason, in order to
define the rated voltage values of components, rated current values of
wires, the size of fuses and the design of control systems that are to be
connected at the output of PV modules, the Isc and Voc values listed
on the module and in the data sheet may need to be adjusted. Refer to
Section 690-8 of the National Electrical Code for an additional
multiplying factor of 125% (80% derating) which may be applicable.
Depending on the installation location, special protection may need to
be taken against lightning and electrical surge. Tight parallel wiring of
the positive and negative conductors can reduce coupling of
interference currents.
3.4 Grounding
For safety reasons, ground the module frame or array before wiring the
circuit in a manner that is in accordance with NEC requirements for
grounding solar electrical systems. When grounding, use material that
is certified according to UL 1703. In addition, grounding hardware must
be compatible with other materials to avoid corrosion due to the use of
dissimilar metals. Grounding should only be performed by a qualified
electrician. Wiring shall be in accordance with the NEC and grounding
method shall also be in accordance with the NEC, article 250 and any
relevant local code and/or ordinance. Grounding method of the frame
of arrays shall comply with NEC, article 250.
Figure 3 – Designated Grounding Holes
It is critical that the grounding system be designed so that maintenance
and/or repair work of one module in the circuit will not interrupt the
grounding of any of the other modules. Each module has two
designated 0.17” grounding holes in the frame, shown in Figure 3, for
use with appropriate grounding hardware (not provided).

See: www.ilsco.com; www.mcmaster.com
Scheuten Solar recommends using a UL listed lay-in ground lug such
as IIsco GBL-4DBT or equivalent, and stainless steel hardware (bolt,
washer, serrated washer and nut). A tooth washer (serrated washer)
should be used between the grounding lug and the module frame
because it is critical that the grounding hardware break through the
anodizing layer and establish electrical connection with the aluminum
frame. Grounding hardware for outdoor use should be stainless steel.
See Table 2 for a list of recommended components. The assembly
must be torqued between 15 in-lbs to 20 in-lbs for #6-32 bolt.
Scheuten Solar recommends that the ground lug be secured using a
bolt, washer, serrated washer and nut assembly. The assembly shall
incorporate some type of locking mechanism (lock washer, lock nut
etc.) to maintain tension between the bolt and the assembly. The
grounding assembly should be designed to prevent components from
wiggling loose, which can jeopardize the integrity of the grounding
system. See Figure 4 below for an example of acceptable means of
equipment grounding. Refer to NEC article 690 on grounding PV
arrays for specific requirements.
Figure 4 – Grounding Example Drawings
1.- Nut 4.- Washer
2.- Serrated Washer 5.- Bolt
3.- Ground Lug
The equipment grounding conductor must not be smaller than No.14
AWG (2.1 mm
2
), must be sized according to the NEC and shall be of
copper, copper alloy, or other material acceptable for use as an
electrical conductor. Only the stainless steel set screw of the lay-in
ground lug provided by the supplier of the grounding material should
be used to securely attach the copper equipment grounding conductor.
Any UL approved PV grounding method and components are also
acceptable for the US and Canada.
4. Maintenance
Generally speaking, solar modules are maintenance free. For smaller
inclination angles, it may be necessary to clean the modules with
plenty of clean water. Avoid any harsh additives. When cleaning the
glass, typical cleaning tools may be used. Any dried dirt residue should
not be scratched or scraped off using sharp tools. Otherwise,
scratches or tears may cause damage to the glass surface. Every once
in a while, the modules should be inspected to assure they are in
proper condition, correctly wired and mounted. While doing so, assure
that they are still firmly attached and that there is no corrosion.
